Loving your pieces…
General Jewelry Care
Jewelry is meant to be worn every day. The oils in your skin actually help prevent tarnish from forming on your jewelry. Most jewelry requires very little care, although as a general rule, it is best to take off your jewelry when swimming, gardening, and moving heavy objects. When not wearing your jewelry, it is best to clean the piece with a polishing cloth and store in an airtight plastic bag. If you happen to have any silica gel packets (the little packets in new shoes) hanging around, throw one in the bag - this will further help prevent tarnish between wears.
Mix a small amount of mild dish detergent with warm water in a bowl. Put the jewelry into the bowl and let sit for a few minutes. Use a soft toothbrush (like a baby tooth brush) or towel to gently clean the jewelry. Remove item from soapy water, rinse it and dry thoroughly with a soft polishing cloth.
Silver tarnishes quickly when it comes into contact with oxygen or sulfur, but stays shiny when worn often thanks to the body's natural oils. The best way to polish silver is with a jewelry polishing cloth, which will resolve almost all of your polishing needs, especially when used often. For silver that needs extra attention, there are a number of specialized commercial products such as Brasso.
Brass may darken with wear, depending on body chemistry. If you don't like the dark patina, try to avoid getting your brass jewelry wet, although constant wear usually keeps brass looking bright thanks to the body's natural oils. Any commercial brass cleaners like Brasso restore brass to its original shine, but a surprisingly easier home remedy is submerging your brass jewelry in Coca Cola for several minutes.
If jewelry is your "thing", you might want to consider a small at-home ultrasonic cleaner. This small and affordable device helps clean the hard-to-get-to areas of intricate jewelry. More importantly, you can clean all of your jewelry at once!
